Building information modeling (BIM) is a promising technology for the construction sector, as it addresses multiple risks, supports decision-making and enhances value. However, its technological and contractual novelties introduce some new risks. To observe the BIM-driven risk transformation, this paper performs a thorough analysis involving international experts and practitioners. Data is collected in the form of open-ended interviews and typeset questionnaire along with case studies of running projects. Results reveal that BIM eliminates a majority of significant risks. Further, the findings fuel a new research problem; the lack of a dedicated BIM plugin for risk management. Responding to it, a theoretical framework is developed to automate the risk management process and improve overall project management practice. It is concluded that construction projects can greatly benefit from an automated risk management system and investment in developing a dedicated plugin is recommended, ensuring an effective penetration of BIM in the construction industry.  相似文献

In project development it is hardly possible to get exhaustive and accurate information. As a result, the situations occur, the consequences of which can be very damaging to the project. Inaccurate evaluation of the strategy related to capital investment and project implementation is one of the reasons why such estimates are not required in practice. Instead, classification approaches may be used for this purpose. Contractors of international construction projects are often faced with complicated situations working in the conditions of uncertainty in construction. One of the potential risk factors is associated with the requirements of contract conditions. One of the major aspects is project or contract management. Project developers need various models of large and complex projects' management. The suggested method for evaluating contract effectiveness may be successfully applied at one of the stages of project management. This paper presents methods of multiattribute comparative analysis (CLARA and UniComBOS methods) of variants of classified investment risks and contract alternatives in investment and building projects of construction. A practical case illustrating the work of the methods is presented.  相似文献

Various risks and uncertainties exist in construction projects. These may not only prevent the projects to be completed within budget and time limit, but also threaten the quality, safety and operational needs. In this context, risk analysis processes are the systematic methods to analyze the potential project risks and develop risk response strategies in order to cope with risks and achieve the desired objectives. This study proposes a new schedule risk analysis method named as judgmental risk analysis process (JRAP) and offers a different project duration equation through JRAP. The process (JRAP) can be defined as a pessimistic risk analysis methodology or a hypothesis based on Monte Carlo simulation that is effective in uncertain conditions due to its capability of converting uncertainty to risk judgmentally in construction projects. A case study has also been developed to show how the proposed process is applied on a construction project and to prove its validity.  相似文献

Currently proposed projects to utilize underground space have provided little information about the necessary security management. This paper discusses risk analysis and probable security management configurations, based on the limited information available. In some cases, security management for underground space is likely to take on a configuration similar to that used for typical buildings on the surface. However, some underground facilities may have the potential for serious danger, created by the interaction of more than two individual risks.  相似文献

Construction projects are being tendered and implemented under different contract systems and payment methods. Design–build has been a popular contract system in recent years. It provides various advantages through entailing the contractor carrying out and being responsible for not only construction but also the design of the work. However, design–build turns out to be a risky system for both owners and contractors unless the risks are identified, analyzed and managed throughout the tender preparation and project execution stages. In this context, this study aims to present a literature survey on the issues of risk, risk management/analysis and the design–build contract system, to propose a schedule and cost risk analysis model, and to show the applicability of these models in scheduling and cost estimation of a fixed-price design–build construction project through a case study.  相似文献

The last decades witnessed an increasing number of large construction programs, which have presented a large number of extra risks in terms of management. This is due to the unique characteristics of programs compared to traditional projects. On the basis of definition of a construction program, a mixed approach was employed in this study to explore the management of delivery risk of a construction program. The main contents include (1) build a delivery risk structure for a construction program as the foundation of risk qualitative and quantitative analysis; (2) analyze risk magnitude and assess the efficiency of delivery methods by using fuzzy logic theory and DEA; (3) conduct a case study of the 2010 Guangzhou Asian Games as an example of construction programs to apply and verify the mixed delivery risk assessment approach developed in this study. The result shows that the separate contracting delivery method which was planned to be used for the 2010 Guangzhou Asian Games is not the best choice, which needs to be improved based on the principles of PM contracting and partner contracting. The mixed approach used in the case study can be employed by practitioners to select an optimal delivery method for other construction programs.  相似文献
